Abstract

A POMDP-based dynamic resource allocation method for a controlled wireless network system belongs to the field of controlled wireless network and communication resource allocation. By constructing the state transition matrix and the feedback observation matrix of the number of users accessing the base station in the cell, the user reliability state probability and the transmission rate obtained by the user based on the number of base station antennas are calculated, so as to determine the maximum benefit when the system obtains the maximum benefit. Optimize the number of user access and complete the optimal resource allocation in the cell. In the present invention, when there are multiple users and a multi-antenna base station in the cell, the user receiving power in the cell is the largest and the user data transmission bit error rate is the smallest, so as to obtain the maximum system benefit as the goal, and determine the final base station antenna opening and the number of users accessing base stations. The invention overcomes the problems of excessive energy consumption, large base station load of a cell, mismatch between antenna opening and user access number, and the like. It has certain advantages in improving user receiving power, anti-interference and overall system benefits.

Description

technical field [0001] The invention relates to a dynamic resource allocation method of a controlled wireless communication network system based on a partially observable Markov decision process (POMDP). Through the POMDP method, a selection scheme that is beneficial to the resource allocation of the wireless communication network is designed, which belongs to the subject Controlled wireless network and communication resource allocation research related fields. Background technique [0002] Mobile communication has developed rapidly in recent decades, and users' demand for wireless communication network service quality is also constantly improving, prompting the wireless communication system to evolve from 2G, 3G, B3G, 4G and 5G, and the main body of the network will also be dominated by voice. The network is transforming to a network dominated by high-speed data. At the same time, mobile multimedia services have higher and higher requirements on bandwidth, and "broadband" ...
